You need the set up for the truck sounds like they retro fitted the axles. you need vacum pump on truck contact quality trailer shop. for kit or quality trailer parts in Azle Texas or redneck. they may be of help instalation depends on truck. Be careful not for the uninitiated. My two cents not cheap.usually used on #10000 axles. No problems with system as long as installed right.
